Gene expression microarray data of bone marrow derived macrophages using GM-CSF(GM-BMMs) co-cultured with E0771 breast tumor cells

ABSTRACT: E-FABP is dominately expressed in macrophages/dendritic cells. Thus E-FABP may play a siginificant role in their immune response to tumor insult. We treated mouse GM-BMMs of different genotype with E0771 breast cancer cells. Then we investigate the global gene expression in these GM-BMMs in response to tumor treatment.

Gene expression microarray data of bone marrow derived macrophages using GM-CSF(GM-BMMs) co-cultured with E0771 breast tumor cells

Project description:E-FABP is dominately expressed in macrophages/dendritic cells. Thus E-FABP may play a siginificant role in their immune response to tumor insult. We treated mouse GM-BMMs of different genotype with E0771 breast cancer cells. Then we investigate the global gene expression in these GM-BMMs in response to tumor treatment. Bone marrow cells were collected from naïve C57BL/6 and E-FABP knockout mice of 6~8 week old. GM-BMMs were derived using GM-CSF (in RPMI1640 with 5%FBS) for 7 days before tumor treatment. After 18hr tumor teatment, GM-BMM total RNA was extracted using RNeasy Mini Kit (Qiagen) and subjected to mouse mRNA Gene expression by Affymetrix microarray.

Quantitative Proteome Responses to Oncolytic Reovirus in GM-CSF and M-CSF-Differentiated Bone Marrow-Derived Cells

Project description:To explore reovirus-macrophage interactions, we performed tandem mass tag (TMT)-based quantitative temporal proteomics on mouse bone marrow-derived macrophages (BMMs) generated with 2 cytokines, M-CSF and GM-CSF, representing anti- and pro-inflammatory macrophages, respectively. We quantified 6,863 proteins across five time points in duplicate, comparing M-CSF (M-BMM) and GM-CSF (GM-BMM) in response to OV. We find that GM-BMMs have lower expression of key intrinsic proteins that facilitate an anti-viral immune response, express higher levels of reovirus receptor protein JAM-A and are more susceptible to oncolytic reovirus infection compared to M-BMMs. Interestingly, although M-BMMs are less susceptible to reovirus infection and subsequent cell death, they initiate an anti-reovirus adaptive T cell immune response comparable to that of GM-BMMs. Taken together, these data describe distinct proteome differences between these two macrophage populations in terms of their ability to mount anti-viral immune responses.

Proteomic analysis reveals distinct metabolic differences between GM-CSF and M-CSF grown macrophages derived from murine bone marrow cells

Project description:Macrophages are crucial in controlling infectious agents and tissue homeostasis. Macrophages require a wide range of functional capabilities in order to fulfill distinct roles in our body, one being rapid and robust immune responses. To gain insight into macrophage plasticity and the key regulatory protein networks governing their specific functions, we performed quantitative analyses of the proteome and phosphoproteome of murine primary GM-CSF and M-CSF grown bone marrow derived macrophages (GM-BMMs and M-BMMs, respectively) using the latest isobaric tag based tandem mass tag (TMT) labeling and liquid chromatography-tandem mass spectrometry (LC-MS/MS). Strikingly, metabolic processes emerged as a major difference between these macrophages. Specifically, GM-BMMs show significant enrichment of proteins involving glycolysis, the mevalonate pathway, and nitrogen compound biosynthesis. This evidence of enhanced glycolytic capability in GM-BMMs is particularly significant regarding their pro-inflammatory responses, because increased production of cytokines upon LPS stimulation in GM-BMMs depends on their acute glycolytic capacity. In contrast, M-BMMs upregulate proteins involved in endocytosis, which correlates with a tendency toward homeostatic functions such as scavenging cellular debris. Together, our data describes a proteomic network that underlies the pro-inflammatory actions of GM-BMMs as well as the homeostatic functions of M-BMMs.

miRNA expression microarrays in GM-CSF or GM-CSF+IL6-induced mouse MDSC

Project description:Myeloid-derived suppressor cells (MDSCs) have emerged as major regulators of immune responses in cancer and other pathological conditions. Multiple factors including cytokines, transcription factors and multiple signaling pathways are involved in MDSC differentiation. Cytokines such as granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin(IL-6) etc could in vitro mediate development of MDSCs.IL-6 with GM-CSF mediated MDSC not only had stronger suppressive function but also the dynamics of their suppressive function was different from GM-CSF alone mediated MDSCs.To found a new regulatory factor (s) in tumor and inflammatory environments, we compared GM-CSF and IL-6 mediated MDSCs with GM-CSF alone mediated MDSCs using lncRNA microarray, miRNA microarrays and protein-coding mRNA microarrays.

Proteomic analysis of GM-CSF and M-CSF polarized bone marrow derived macrophages

Project description:Bone marrow cells were isolated, primed with M-CSF (M-BMDM) or GM-CSF (GM-BMDM) and cultured for 7 days. The proteomic difference between GM-BMDM and M-BMDM were analyzed to describe the phenotye and function of two types of macrophages.

GM-CSF nitration is a new driver of myeloid suppressor cell activity in tumors

Project description:Reactive oxygen species, including RNS, contribute to the control of multiple immune cell functions within the tumor microenvironment (TME). Tumor-infiltrating myeloid cells (TIMs) represent the archetype of tolerogenic cells that actively contribute to dismantle effective immunity against cancer are among the cells most influenced by these molecules. TIMs inhibit T cell functions and promote tumor progression by several mechanisms including the amplification of the oxidative/nitrosative stress within the TME. In tumors, TIM expansion and differentiation is regulated by the granulocyte-macrophage colony-stimulating factor (GM-CSF), which is produced by cancer and immune cells. Nevertheless, the role of GM-CSF in tumors has not yet been fully elucidated. In this study, we show that GM-CSF activity is significantly affected by RNS-triggered post-translational modifications. The nitration of a single tryptophan residue in the sequence of GM-CSF nourishes the expansion of highly immunosuppressive myeloid subsets in tumor-bearing hosts. Importantly, tumors from colorectal cancer patients express higher levels of nitrated tryptophan compared to non-neoplastic tissues. Collectively, our data identify a novel and selective target that can be exploited to remodel the TME and foster protective immunity against cancer.

Molecular profiling of SV-BR-1-GM, a clinically effective GM-CSF-secreting human breast cancer cell line

Project description:The SV-BR-1 cell line was derived from a chest wall lesion of a breast cancer patient. SV-BR-1 cells were stably transfected with CSF2 (encoding GM-CSF), resulting in the SV-BR-1-GM cell line. Following irradiation to prevent cell replication, both SV-BR-1 (Wiseman and Kharazi, The Open Breast Cancer Journal, 2010, 2, 4-11) and SV-BR-1-GM (Wiseman and Kharazi, Breast J. 2006 Sep-Oct;12(5):475-80) cells have been applied as whole-cell therapeutics in clinical trial settings for advanced breast cancer. Molecular profiles of non-irradiated SV-BR-1-GM cells have been established from various manufacturing lots via Illumina HumanHT-12 V4.0 expression beadchip arrays (GPL10558). A key finding from the study is the identification of an immune signature expressed in SV-BR-1-GM cells which includes the MHC class II factors HLA-DMA, HLA-DMB, HLA-DRA, and HLA-DRB3. Since tumor regressions were apparent in clinical trial subjects matching at an HLA-DRB3 allele with SV-BR-1-GM we hypothesize that (partial) HLA matching is needed for maximal tumor-directed clinical responses to occur.
